What microformats2 elements does the analyzer parse?

It parses h-entry, h-card, and h-feed classes, resolving text properties (p-*), absolute URLs (u-*), datetime values (dt-*), embedded markup (e-content), and implied values.

How does the tool handle Webmention validation?

It verifies that source and target parameters are valid URLs, confirms source does not equal target, checks fragment handling, and locates rel=webmention endpoints.

What ActivityPub objects and activities are generated?

Standard posts produce an AS2 Note wrapped in a Create activity, while entries with u-like-of or u-repost-of produce Like or Announce activities referencing the target object.

Does the analyzer generate Micropub request payloads?

Yes, it creates exact W3C-compliant JSON create payloads ({type: ["h-entry"], properties: {...}}) as well as update and delete action structures.

What is reply-all routing?

It maps outbound notifications for every in-reply-to, like-of, repost-of, and u-syndication link found in the entry, specifying Webmention targets and Fediverse bridging paths.

Parse microformats2 (h-entry/h-card), validate Webmention/IndieAuth/Micropub/Microsub, emit ActivityPub Object+Activity dual views and reply-all routing — W3C-spec accurate

Details

What this tool helps you do

Bridge an IndieWeb page into the Fediverse — with a real microformats2 parser and the W3C protocol checks that real bridges run.

What it does:

mf2 parse tree: parses h-entry / h-card / h-feed markup following the microformats2 parsing algorithm — p- (value-class, data/input value, img-alt substitution), u- (href/src/value precedence, resolved absolute against your base URL), dt- (time[datetime]), e-content (html + value), nested microformats with prefix-derived value, implied name/url/photo.
Webmention (W3C Rec 2017): validates source/target (MUST be URLs, receiver MUST reject source == target), fragment-insensitive target support checks, and discovers rel=webmention endpoints in the page.
IndieAuth (W3C Rec 2018): discovers rel=authorization_endpoint / rel=token_endpoint and the Micropub/Microsub endpoints; explains the authorization-code + PKCE S256 flow the endpoints implement.
Micropub (W3C Rec 2017): builds the exact JSON create request ({type:["h-entry"], properties:{…}}) for the parsed entry, plus update (replace/add/delete) and delete/undelete action templates.
Microsub (IndieWeb draft): derives a channel layout for the feed and documents order=published vs the default received-order timelines.
ActivityPub dual view (W3C Rec 2018): emits the AS2 Object (Note with inReplyTo, attributedTo, Public addressing via as:Public) and the wrapping Activity — Create, or Like/Announce when the entry carries u-like-of/u-repost-of.
Reply-all routing: for every in-reply-to / like-of / repost-of / u-syndication target, emits the notification route — a Webmention to the target's discovered endpoint, plus Bridgy-Fed-style Fediverse bridging suggestions and ActivityPub relay guidance.

Honesty note: "Apenode" is not a Fediverse/W3C standard — it was the 2015 pre-release name of the Kong API gateway. The real relay concept here is the ActivityPub relay: a server that follows actors and re-Announces their activities so new instances can bootstrap federation. The routing output reflects that reality.
